As information literacy instruction is also a form of storytelling, animated GIFs might be a good format for library tutorials. Suhr’s reasons included:
A group of pictures gives immediate feedback as to how much information is being conveyed. A screencast, on the other hand, doesn’t give much of a clue as to what the user is committing to.
Pictures have natural break points between steps.
A series of images enhances closure, which is the phenomenon of observing the parts but perceiving the whole. Comics artists employ closure by carefully sequencing panels and knowing what to keep “off-screen.”
A series of animated GIFs combines closure with the dynamic element of video.

GIFs (and their resurgence) are an interesting hybrid approach falling somewhere between videos and images. One can see how modelling videos after animated GIFs could be a good way to provide quick, just-in-time information.
